Question 380520
2.) Here is a graph of p(x).
It has a real root between 2 and 3. 
The other two roots are complex. 
I'm not sure I understand your question?

3). You are missing an operator in your equation or something is wrong with your equation. 
After the y on the right hand side you should have an operator (+,-,*,/) and then I think you mean to write the absolute value of the negative of the absolute value of negative x, but I'm not sure. 
y= y|-|-x||
